One will be able to obtain, e.g.:

zinit fzf<Alt>-<Shift>-A
    » zinit junegunn/fzf
zinit cd rip<Alt>-<Shift>-A
    » zinit cd BurntSushi/ripgrep

and so on. The <Alt>-<Shift>-A shortcut works with ALL commands,
regardless if it's zinit command or not.

Two autoloaded functions added, ziactioncomplete (the proper imple-
mentation of the main features) and ziprocessbuffer (a very useful
library function that takes care of $BUFFFER/$CURSOR processing).

Also Feature: Cycling and ice-completion (<Alt>-<Shift>-C).

Cycling will allow to choose a particular match, say for, e.g.:
zinit at<Alt>-<Shift>-C
    »   zinit atclone<Alt><Shift>-C
    » zinit atinit<Alt>-<Shift>-C

Alias all plugins with ~plgname to point to their directory.
